[Solved] Help. How to keep actors in place?

I am making a sliding puzzle game but whenever the user slides a piece.....it sometimes bounces back. I am using push -actor. I have attached a short video clip of the problem.

....and just to add. .. The actors are set to normal and friction @=0, no gravity and bounce @=0.

For this game you don't need collision shapes. Also I would use the "slide actor by x and y over x seconds" block under actors-->tweening-->slide. That way you can precisely choose to how many pixels it is moved.

Thanks....but I was avoiding that method because I am not so good with tweening XD.....also I have a player that needs the collisions for going through the maze.

I have made it work.   Switched to simple physics( though this may not matter....might just be placebo XD ') )..... instead of using push actor, I used x speed and set conditions to remove unneeded X and Y speed depending on which side the actor has collided. It now works silky smooth

This was actually a nightmare to do with unity.....could not get swipe to work with a specific actor. Stencyl is amazing.... I think I'll complete and publish the game with it XD
